STMicroelectronics MLPF-WB-04D3 2.4GHz Low Pass Filter has an impedance-matching network and harmonics filter to enhance RF performance for the STM32WBA52. The STMicroelectronics MLPF-WB-04D3 filter uses IPD technology on a non-conductive glass substrate to optimize RF performance effectively. The device features a 50Ω nominal impedance on the antenna side and a deep rejection harmonics filter.
